ADJUSTABLE TRACE-FASTENER FOR HAMES.

Specification of Letters Patent.

Patented Jan. iii, 19145.

Application filed July 28, 1915. Serial No. 42,262.

To all "whom it may concern:

Be it known that I, SAMUEL L. Cuow, a citizen of the United States of America, residing at Seymour, county of Jackson, State of Indiana, have invented a certain new and useful Adjustable Trace-Fastener for Flames, of which the following is such a full, clear, and eXact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an adjustable trace fastener for hames.

It has been usual heretofore to provide a hanger with an elongated staple or plate to which the traces may be adjustably attached so as to varv the point of draft. In such devices it has been necessary to provide some auxiliary means for retaining the loop or hook which secured the traces in position so that the said hook or loop will not become accidentally disengaged from the plate or staple.

The object of my invention is to obviate the use of any such auxiliary device, so as to hold the loop or hook in position by its own resiliency.

In the accompanying drawing which illustrates a portion of a hame provided with fastening device made in accordance with my invention, Figure 1 is a side elevation, Fig. 2 is a front view, Fig. 3 is a detailed View of one of the loops for fastening the trace, and Fig. 4- is a section taken on the line ll of Fig. 1.

Like marks of reference refer to similar parts in the several views of the drawings.

5 represents a portion of a hame to which is secured by means of screws 6 an elongate plate 7. This plate 7 is preferably triangular in shape, as best shown in Fig. 4: of the drawing, and is provided at suitable regular intervals with openings 8 to receive the trace fastening means, hereinafter clescribed. At the apex of the plate 7 is a rounded portion 9 forming a bar around which are adapted to pass a pair of hooks 10 formed on the end of a loop 11, which is adapted to be attached to the trace or tug. It will be evident that by passing hooks 10 through two of the openings 8 and turning loop 11 through an angle of about 186 the loop will be brought into position, as

best shown in Fig. 8 of the drawing. These 3 cam surfaces are of such size that their outer faces are slightly a greater distance apart than the two outer faces of a pair of openings 8. When one hook 11 is moved into position the cam surfaces 12 will cause the hooks 10 to move slightly together against the resiliency of the material of the loop. IVhen the parts have reached the position shown in Fig. 1 these cam surfaces 12 will lie between the two sides of the plate 7, so as to hold the loop 11 in position until a suitable pressure is brought to bear upon it in the proper direction to secure its removal. The lower end of the plate 7 may be provided with an opening 13 receiving a ring 14 for the neck yoke strap.

The operation of my invention will be evident: To secure the loop 11 in position, or remove it, it is only necessary to use sufficient force to slightly compress the bifurcated ends of the loop. This force is surlicient to prevent the accidental removal of the loop, either when the device is in use, or whenit is laid aside.

Having fully described my invention, what I claim as new and desire to secure by Letters-Patent of the United States is:

1. The combination with a hame, of an adjusting member secured to said hame and provided along its length with a plurality of engaging points, and a resilient trace fastener adapted to be sprung into engagement with said points and retained in position by its own resiliency.

2. The combination with a hame, of an adjusting member, and a trace fastening member, said trace fastening member being provided with cam surfaces adapted to be sprung into engagement with the said adjusting member and retained in position by 1 the resiliency of the said trace fastening member.

8. The combination with a hame, of a plate carried thereby and forming an adjusting member, said plate being provided with a plurality of openings, and a bifurcated trace fastening member adapted to be sprung into engagement with said opening and retained in position by its own resiliency.

4:. The combination With a hame, of a plate carried thereby and forming an adjusting member, said plate being provided With a plurality of openings, and a loop for fastening a trace to the said plate, said loop having on each end a hook adapted to engage with the openings in said plate, said hooks being provided With. cam surfaces adapted to be sprung into engagement with the openings of said plate and retained in 10 position by the resiliency of said loop.

In testimony whereof I have hereunto set my hand and affixed my seal in the presence of the two subscribing Witnesses.
